Improvement in pumps



UNITED STATES PATENT OEEIcE.

EDWARD B. JUCKET, OF ROXBURY, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND HUNNEMAN St CO. y

IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 57,635, dated August 28, 1866.

To all whom it may concern:

Be it known that I, EDWARD 1 3. JUcKET, of Roxbury, in the county of Norfolk and State ot' Massachusetts, have invented an Improved D0ubleActing Force-Bum p, suitable for steam nre-engines or various other uses; and I do hereby declare the same to be full.)7 described in the following specification and represented `in the accompanying drawings, of whichi Figure l is a longitudinal section, and Fig. 2 a transverse section, of such pump. Fig. 3 is a transverse section of one of its end valvechambers.

In such drawings, A denotes a cylinder or barrel, open at both ends, and provided with a plunger or piston, B. This barrel is arranged concentrically within a segmental case, U, which, by means of three vertical partitions, a b a, and two inclined and dial ones, c c, arranged within it, as represented, is divided into two valve-chambers, D D, two induction -chambers, E E, and one eduction-chamber, F. The two valve-chambers have the eduction-chaniber between them, and each of them opens directly into one of the two induction-chambers.

Below the two inductionchambersV is an induction valvechamber, G, which opens, through valveseats d d, directly into both ot' the induction-chambers, there being a valve, e, to each of such openings, and such valve being arranged within the chamber G.

Each of the vertical partitions a a has one or more series of openings,ff, leading through it, there being' a valve, g, to each of such openings or separate series of openings, such valve being arranged within the chamber D next to such partition a.

Thereis an ed notion-passage, h, leading out ofthe top of the chamber F. The pistoitrod t' works through one head, 7c, of the segmental case. Each end of the pump-barrel A terminates at a distance from the next adjacent end of the case (l.

When a reciprocating rectilinear movement is imparted to the piston, and the pump is connected with a reservoir of water by a conduit opening into the lower valve-chamber, the water will be alternately driven into and expelled from thebarrel on each side of its piston-head, and will be thrown into the eduction-chamber, from whence it will be expelled through its escaping' opening or passage.

This formation otl the pump or arrangement of its parts enables all of it, with the exception of the piston, the valves, and the heads of the case, to be cast in one piece ot' metala matter ot' much importance as regards economy of construction--and besides it is an arrangement which is very efficient in operation.

I make no claim herein to the inventions described in the United States Patents Nos. 28,644 and 45,722.

What I claim is- My improved double-acting force-pump, or peculiar arrangement ot' the valve-chambers D D G, the induction chambers or passages E F, and the pump-barrel A, as described, such valve-chambers to be provided with valves and valve-opening's, and such barrel to have a piston to operate as specied.
